Hitchcock had been working on the story for nearly nine years prior to meeting Lehman.[citation needed] Otis Guernsey was the American journalist who had the idea which influenced Hitchcock, inspired by a true story during World War II when British Intelligence obtained a dead body, invented a fictitious officer who was carrying secret papers, and arranged for the body and misleading papers to be discovered by the Germans as a disinformation scheme called Operation Mincemeat. Guernsey turned his idea into a story about an American salesman who travels to the Middle East and is mistaken for a fictitious agent, becoming "saddled with a romantic and dangerous identity".
